log file name not change after rollover TimeBasedRollingFileAppender about log4cplus HOT 3 OPEN

I think this works as intended. The filename is constant, e.g., app.log. When schedule period ends, the filename, gets renamed to scheduledFilename and the new current period uses the filename for logging again.

from log4cplus.

I get it. If the initial filename is not empty, then this logic is correct.
My issue might be that the initial filename was not provided in the configuration file, which caused the problem.

Is it more reasonable to prohibit running when the filename is empty rather than continuing to run, which may potentially cause errors?

encountered another problem
If RollOnCloseis on, subsequent logs for the day will overwrite the previous one.
If RollOnCloseis off, and the app was closed normally the day before yesterday and reopened the next day, rolloverwill never be triggered, and all logs will be in the same file specified by filename.
The following is my configuration file, I do not know what is wrong.
